[Bug other/23430] New: configure should allow --comment option

[flash at pobox dot com]

When trying to keep track of various builds of GCC, it would be convenient to be able to store a 
comment to be read back with -v.  Since -v echoes the full configure command line, all that's required 
is not rejecting an argument containing the desired comment.
    I'll upload a patch which permits this.  All it does is add a --comment option which does nothing; it's 
just seventeen copies of the following, one for each configure file:

  --comment=*)
     ;;                #Do nothing; this is just so that the comment will show up with -v. 

    There may be an easier way for maintainers to patch this, using auto-configuration; but I've never 
run that.  There are workarounds, such as embedding configuration information into directory names, 
but this approach seems simpler.
    A patched checking=yes build passed make check.

One thing you could do is replace the place where the configure options where, unless you want the 
configure options also.

Use --with-comment instead.

[Bug bootstrap/23430] --with-comment configure option isn't documented

Thanks, --with-comment seems to work, but it doesn't seem to be documented.  Grepping both the 
documentation and source folder didn't find it; Googling for it turned it up in the context of MySQL, but 
not GCC.  So I'm re-titling and reopening the bug.  I think the option should be listed in --help, but it 
certainly needs to be documented somewhere.

The main reason why it is documented, it is not a real configure option.   But we (autoconf) ignores 
unknown --with options.
